The present invention provides a new electronic circuit board and a method of using such board to test electronic devices at elevated temperatures. The board comprises a steel base having a dielectric coating layer and a circuit formed on the layer. The circuit includes a connector region for attachment to an external electrical source and a mounting region for mounting sockets for supporting, powering and monitoring the electronic devices during elevated temperature testing. The board displays a leakage current of less than 10 &#x3bc;Amps at 350&#xb0; C.

Method and device for testing electronic devices

An electric circuit board to test electronic devices at elevated temperatures. The board comprises a steel base having a dielectric coating layer and a circuit formed on the layer. The circuit includes a connector region for attachment to an external electrical source and a mounting region for mounting sockets for supporting, powering and monitoring the electronic devices during elevated temperature testing. The board displays a leakage current of less than 10&mgr; Amps at 350&deg; C.

Device for testing electronic devices

A circuit device and a method for providing an interface between a circuit device comprised of a porcelain enameled metal substrate and an external electrical conductor such as a wire or a lead. An aperture is formed in the substrate at the location where the connection is desired. An eyelet is then placed in the aperture. Crimping or other means are used to form a mechanical connection to the substrate and causes the eyelet to be retained in the aperture. The wire or lead of an electronic component is then inserted into the eyelet. The wire or lead is then soldered to the eyelet providing a joint of high mechanical strength.

The present invention provides an electrically heated air freshener for producing a scent comprising a housing having a receptacle for supporting a fragrance block, the fragrance block comprising a material that volatilizes upon heating and a porcelain enamel metal substrate comprising a metal substrate having a porcelain enamel coating bonded thereto. The porcelain enamel coating has bonded thereto a resistance strip for generating heat upon application of an electrical current and a conductive strip for conducting electrical current to the resistance strip.

Electrically heated air fresheners

A touch control panel for use in controlling an electrical device such as a washer, dryer, stove, microwave or related piece of electrical equipment. In a preferred embodiment, the touch control panel comprises an outer panel formed of flexible aluminum. The outer panel includes an outer and an inner surface. The inner surface of the aluminum panel includes a first circuit formed along at least a portion of the surface. The control panel also includes an inner support panel comprising a porcelain enamel metal substrate. The porcelain enamel metal substrate affords a highly durable and rigid degree of support to the control panel. The support panel has an inner surface which is spaced from and disposed substantially parallel to the inner surface of the outer panel. The inner surface of the metal substrate has formed along at least a portion thereof a second circuit. Upon application of tactile pressure upon the outer surface of the outer panel, the first circuit contacts the second circuit. Upon release of the tactile pressure, the first circuit disengages contact with the circuit.
